Driven by an explosion of data creation and retention needs, hard-disk-drive (HDD) storage capacities and data-center densities are rapidly expanding thanks to a technology called shingled magnetic ...

Use left and right arrow keys to seek audio. We've covered Seagate's HAMR, or Heat-Assisted Magnetic Recording, tech for HDDs, which is set to breathe new life into traditional platter-based storage ...

Research groups have made a breakthrough in the field of hard disk drives (HDD) by demonstrating the feasibility of multi-level recording using a three-dimensional magnetic recording medium to store ...

Microwave-Assisted Magnetic Recording (MAMR) employs a high-frequency magnetic field to lower the effective switching field of recording media, enabling the use of smaller, high-coercivity grains and ...

Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR). This advancement is ...

In a recent article in Acta Materialia authors from Seagate, NIMS and Tohoku University demonstrated two-layer heat assisted magnetic recording. The research team combined experimental measurements as ...

Forward-looking: Magnetic storage technology in hard disks has undergone significant evolution in recent years. Following Perpendicular Magnetic Recording (PMR), Shingled Magnetic Recording (SMR), and ...

Heat-assisted magnetic recording harnesses a near-field optical transducer to deliver nanoscale heat spots that locally raise the recording medium’s temperature toward or above its Curie point, ...

Schematic view of (top) currently used HAMR and (bottom) three-dimensional magnetic recording systems. In the three-dimensional magnetic recording system, the Curie temperature of each recording layer ...
